Enter the molar flow value in mol/second in the input field.
-
Select the input unit as mol/second [mol/s].
-
Choose the output unit as examol/second [Emol/s].
-
Click the convert button to perform the conversion.
-
View the result displayed in examol/second for your reference.
Key Features
-
Supports precise conversion between mol/second and examol/second molar flow units.
-
Easy-to-use interface for quick and accurate unit conversions.
-
Browser-based solution requiring no installations or software downloads.
-
Ideal for chemical engineering, electrochemistry, astrophysics, and computational modeling.
-
Allows expressing extremely large molar flow rates conveniently using exa-scale units.
Examples
-
5 mol/s converts to 5 × 1e-18 Emol/s = 5e-18 Emol/s.
-
1,000 mol/s converts to 1,000 × 1e-18 Emol/s = 1e-15 Emol/s.
Common Use Cases
-
Specifying feed or product rates in chemical reactors where stoichiometric calculations use molar flow rates.
-
Reporting gas flow rates for process equipment requiring the amount of substance measurement.
-
Quantifying reaction rates in electrochemical cells or catalytic converters in units of mol/s.
-
Expressing extremely large molar flows in astrophysics and planetary science such as atmospheric escape rates.
-
Scaling and unit conversions in theoretical models handling exa-scale quantities efficiently.
Tips & Best Practices
-
Use mol/second units for typical laboratory or industrial chemical reaction rates for clarity.
-
Switch to examol/second when dealing with extremely large flows to simplify numerical handling.
-
Double-check unit selections to ensure proper conversion context, especially in scientific calculations.
-
Refer to the conversion formula 1 mol/s = 1e-18 Emol/s for correct scaling guidance.
Limitations
-
Examol/second units represent extremely large flow rates and are unsuitable for typical laboratory or industrial scale applications.
-
Using Emol/s for small or moderate values can lead to loss of interpretability due to scale differences.
Frequently Asked Questions
-
What does mol/second measure?
-
Mol/second (mol/s) is the SI derived unit measuring the amount of substance passing a point or being produced/consumed per second.
-
When should I use examol/second?
-
Examol/second is used to express extremely large molar flow rates in fields like astrophysics or high-level computational models.
-
How are mol/s and Emol/s related?
-
1 mol/s equals 1e-18 examol/second, meaning Emol/s expresses quantities on an exa-scale, one quintillion times larger.
Key Terminology
-
mol/second [mol/s]
-
An SI derived unit measuring the molar flow rate, or the amount of substance in moles passing a point per second.
-
examol/second [Emol/s]
-
An SI-derived unit equal to 10^18 moles per second, used for expressing extremely large molar flow rates.
-
Molar Flow Rate
-
The quantity of substance (in moles) moving through a specific point or produced/consumed per unit time.
